If the average innings in a career were higher in earlier years, it would indicate that pitchers got more out of their arms than they do today. The measure of durability isn't seasons. It is innings pitched. I am not arguing that pitching isn't inherently dangerous. I am also not arguing that today's training and conditioning methods are not superior to the past. What I am suggesting is that the approach to pitching may be the culprit. Today, scouts are putting radar guns on kids at age 13. That is ridiculous. The emphasis for the last 25 years has been velocity from a very early age. The empasis for kids should be learning to throw strikes and command the zone. Any scout worth his salt can tell if a kid has good velocity without putting a gun on the kid. The kid's hear about the numbers that they are hitting on the guns and they are trying to tick up the velocity when they should be striving to throw strikes and get outs. Pitchers don't pace themselves today like they did years ago. If a pitcher's velocity is down a few ticks, they take him out and send him for xrays. In the 60's and 70's, they threw more secondary or offspeed pitches to get through an outing when they were a little tired. Seaver and Ryan weren't outliers. They were standouts, but not because they were workhorses. Every staff had guys that pitched a lot of innings. The Cards had Gibson and Carlton. The Dodgers had Drysdale, Koufax, Sutton and Osteen. The Giants had Marichal and Perry. The Twins had Dean Chance, Kaat, and Jim Perry and then Blyleven. The Tigers had McLain, Lolich and Wilson. The Mets had Seaver and Koosman. Even the lowly Guardians had Sam McDowell and Tiant. I could go on and on. Some of them were finished by age 30, but even those guys got 6-8 good seasons in the bigs.
